    My guess is that its the way Expose events are propagated, but I'll
    have to check. When I wrote the Formbrowser (yes, I'm largely to
    blame for this crock), I basically just copied TC's TabFolder object
    and added some scroll bars. It was for a specific project with a
    small number of relatively simple child Forms. What I did probably
    doesn't generalize very well and should be redone.

    In order to expedite matters, if you could forward to me some *simple*
    example code that exhibits the problem, I'll take a look at it. I
    don't know when I'll get to it in earnest, since I'm gearing up for
    Supercomputing 2000 (Anyone going? I'll be at the NPACI booth for a
    bit of the time helping to show teleoperation of our 400 KeV electron
    microscope via the Internet) and have several projects that I need to
    put the finishing touches on.
